Study Endpoints
Primary Endpoints
Objective Response Rate (ORR)
From randomization until disease progression or loss of clinical benefit (up to approximately 7-9 years)

ORR, defined as the proportion of participants with a complete response or partial response on two consecutive occasions \>=4 weeks apart during Stage 1, as determined by the investigator according to RECIST v1.1.

Secondary Endpoints
Progression Free Survival (PFS)
Randomization to first occurrence of disease progression or death from any cause in Stage 1 (up to approximately 7-9 years)
Overall Survival (OS)
Randomization to death from any cause (up to approximately 7-9 years)
OS at Specific Timepoints
Randomization to a specific timepoint, such as Month 6
